TITLE : Mapping the Large-Scale Structure around Galaxy Clusters

 

ABSTRACT : Galaxy Clusters, the largest gravitationally bound systems in the universe, are important tracers of large-scale structure. I will briefly review the history of galaxy redshift surveys focusing on clusters of galaxies, and discuss the results on the comparison of the matter distribution from our MMT/Hectospec cluster redshift surveys with that from weak-lensing surveys.
